Basic Antenna Trainer

Basic Antenna Trainer is basically a tool for different experiments in the laboratory for students. It is widely used in understanding the working of different Antennas in UHF-Microwave. Firstly, the trainer is rotated 3600 and after that we can monitor the strength of signal on the receiver.

It is available with a polar plotting software which is used to save the readings manually. This basic trainer trainer has the two tripods which are used for mounting the transmitting antenna and for mounting the receiving antenna and relevant accessories/ cables etc.
